Title: Improvements in or relating to tyre inflation hose equipment
Inventor: BROWN THOMAS
IPC: B60S5/04
Filed: 1956-05-09
Abstract: 792,397. Pipe joints. PNEUMATIC COMPONENTS, Ltd. Dec. 24, 1956 [May 9, 1956], No. 14336/56. Class 99(1). In tyre inflation equipment comprising a hose 2 having concentric passages 3, 4 delivering pressure air from a supply to an inflator and from a tyre to a gauge 1 respectively, members 9, 23 secured to the supply and gauge and to the hose respectively and held together by a union nut 22 have side-by-side registering air passages each surrounded by a sealing ring 27 and 33 projecting from the end face of one part and compressed between that end face and the end face of the other part when the joint is made, the passages being connected to the outer and inner passages of the hose respectively and a vent hole 34 being provided in the union nut. An inclined boss 9 has two parallel ports 17, 18 which connect to air supply passage 19 and gauge passage 21 respectively and is threaded externally to receive the union nut 22 which secures the connecting barrel 23 to it. The supply port 17 is tapped for the insertion of a tube 24 that protrudes from its end face 26 and enters a clearance hole and air passage 28 in the barrel. The sealing ring 27 surrounds the tube 24 and projects from a recess in the face 26 and is compressed against the face 32 of the barrel. The gauge port 18 has a clearance hole and air passage 29 which similarly receives a tube 31 tapped into the barrel 23 and is sealed by a ring 33 which projects from a recess in the barrel face 32 and is compressed against the boss face 26. When secured as shown the rings prevent face to face contact and the space surrounding the rings is open to atmosphere through a hole 34 in the union nut so that if the seal 27 on the pressure supply is defective, escape of compressed air can be achieved without damaging the gauge. The supply port 17 leads through a passage 36 to an annular space 37 to which the hose 2 is connected by a fitting 38 held by a union nut 39, and connects with the outer tube 3 of the conduit. A screwed thimble 41 enters a threaded bore in the barrel 23 centrally of the space 37 from which it is sealed by a taper sleeve 44, and the inner air passage 4 of the hose 2 connects through the bore of the thimble 41 and communicates by an oblique passage 42 with the tube 31. By means of a hand valve air under pressure is supplied through the port 17 and passages 36, 3 to a tyre and the pressure therein communicates through passages 4, 42, 31 and the port 18 with the gauge, the two conduits being sealed from each other.

Patent GB-631765-A (GB)
Title: Mordant dyeing process and product
IPC: D06P1/36
Filed: 1947-05-30
Abstract: A metal carbonyl, e.g. iron carbonyl, is incorporated in a synthetic hydrophobic fibrous material, e.g. cellulose acetate, nylon or " Vinyon " (Registered Trade Mark) in the spinning operation.  The fibres obtained have an affinity for mordant dyestuffs.ALSO:Textile fibres, including cotton, cellulose acetate, regenerated cellulose, nylon and "Vinyon" (Registered Trade Mark) fibres are dyed by means of mordant dyestuffs with the use of a metal carbonyl of the iron group as a mordant.  The fibrous material containing the carbonyl compound may be treated with sodium hydrosulphite before application of the dyestuff.  The carbonyl may be applied in the liquid state or, preferably, as an emulsion in water.  Suitable metal carbonyls are iron pentacarbonyl, nickel tetracarbonyl and cobalt carbonyl.  The mordant may be applied before the dyestuff or dyestuff and mordant may be applied together, but when used for printing they are preferably applied together as an emulsion, the dyestuff being in the aqueous phase and the carbonyl in the oil phase.  In examples: (1) cellulose acetate is immersed in an aqueous emulsion of iron carbonyl to which sodium hydrosulphite is then added, and then dyed with omega-isonitroso-omega-cyano-acetophenone; (2) cellulose acetate is immersed in a bath consisting of an aqueous emulsion of iron carbonyl to which is added sodium hydrosulphite and alpha-nitro-beta-naphthol; (3) the previous example is repeated with 1-(omega-isonitroso-omega-cyano-aceto)-2-naphthol methyl ether as the dye; and (4) cellulose acetate previously treated with iron carbonyl as in (1) is dyed with a specified diazo dyestuff.  The Specification as open to inspection under Sect. 91 refers also to the dyeing of regenerated cellulose.  This subject-matter does not appear in the Specification as accepted.

Abstract: 131,752. Shapiro, H. Sept. 10, 1918. Folding edges of sheet material.-A machine for folding material into a band with overlapping sides comprises a guide adapted to fold the sides of the material upwards, pieces for folding down the upturned sides, and means for preventing the sides from interfering with one another, including a guide-finger with an overturned head, into which one side passes so that its edges is curved away from the other side and is guided thereunder; a forked finger engages and guides the upper side, and the folded band passes through a box-guide of adjustable width and between pressing-rollers. The material passes from a roll, over and under rollers 15, and through a folding-guide 16, which is mounted on an inclined frame 10 and has a flat bottom 17 and vertical side members 18 increasing in height from the entrance end of the guide. The sides of the material are turned up by the members 18 and are turned down inwards by adjustable folding-pieces 22a, of which only one is shown, the flat central portion A of the material passing under a tongue 21, which serves as a. gauge for the width of the folded band. The side C, which is to be folded under the side B, passes under a guide-finger 25 provided with a downwardly and outwardly curved edge 25<a>, which bends the edge away from the side B. This side is engaged by the forked end of a guide-finger 28 and guided over the side C. The folded material then enters a box or tubular guide comprising a base 30 fixed to a flat frame 11, a side piece 31 adjustably secured to the base and having a doubled edge 32, and a movable side piece 33 with a guided extension 34 connected by a link 37 to a lever 41 whereby the side piece may be adjusted to determine the width of the guide, a scale 43 and pointer 44, and a fixing-screw 42 being provided. The inside of the fold of the material is pressed against the side piece 33 by a pivoted knife 45 clamped in adjusted position by a thumbscrew 46. If the material is hemmed, the enlarged head 28' of a guide 27' rests on the inner side of the hem and keeps the band smooth and even as it enters the tubular guide. The folded band is pressed, especially at its edges, by passing it between rollers 49, which are geared totogether and driven by power applied to a gearwheel 54 so that they draw the material through the machine. The upper roller has a groove 53 to allow for the extra thickness at the overlapping portions of the band.

Title: Improvements in plate or film holders for photographic cameras
IPC: G03B17/26
Filed: 1943-09-09
Abstract: 577,995. Photographic cameras ; plate and film holders. WOOD, A. F., and CELESTION, Ltd. Sept. 9, 1943, No. 14832. [Class 98 (i)] A plate or film holder, of the kind having a hinged cover to permit loading and a draw slide to permit exposure, has latch members on cover and slide which co-operate to prevent movement of either cover or slide unless the latch members are disengaged, these members being so placed on the holder that they are inaccessible to direct manipulation when the holder is in position in a camera having a closed back. Release of the latch is effected by a rotatable cam on the camera, operable from the outside, which cam may serve also to lock in closed position a resilient light-trap through which the holder is inserted into the camera. As shown, the holder has a draw slide A to which is secured a sprung-up latch plate B, and a cover D hinged at d which has a transversely-slidable latch plate C hooked at CB to engage a slot b<1> in plate B to retain the'slide A, the plate also having lugs CE which in the same position of the plate prevent opening of the cover D. For loading the holder, plate B is depressed to free it from the hook CB, and plate C is slidden to register the lugs CE with notches E in the cover, permitting this to be opened. After loading, these operations are reversed to lock cover and slide ; and after inserting the holder in the camera, plate B is depressed by the aforementioned cam to permit slide A to be withdrawn for exposure. In the holder, the sensitive plate or film is pressed against the focal window I by a spring G on the cover D, which is lined with a felt or plush sheet F. The light-trap on the camera through which the holder is inserted may consist of two strips of plush-covered material attached, as by hinging along one edge, one on each side of the insertion aperture, and drawn together along their opposite edges as by springs so as to form a V-channel open outwardly. On inserting the holder, it opens the apex of the V to force a passage; and when inserted, it is held by engagement of one of the strips with its end. Accidental withdrawal of the holder when withdrawing slide A is prevented by adapting the cam which unlatches the slide to lock the light trap by the same movement.
